This is an intermediate-level erhu textbook from the Shanghai Conservatory of Music in China. It is a non-commercial textbook, including 6 music CDs with 138 songs and sheet music. I bought it for practicing the erhu, but I hardly used it, so it's in unused condition. The outer box has no noticeable stains, and the sheet music and CDs inside are also in good condition. If you are interested, please consider it.
